I need a diagnostic program that will test the entire RAM space on the
ST. I would like one that tests the low (protected) memory as well as the
higher memory. I need to check for intermittent memory trouble, so I'd be
running this test for several days (or until failure). It would be sufficient
for the program to print the failing address and pattern to the printer
rather than maintaining a screen display. I thought I had one of these.
I know I wrote one back a few years ago, but I cannot find it. I would
like to know if one is available PD or for a low price.
Also, is there any test that would recognize slowed RAM access? When I'm
in low-resolution color, I get funny vertical intensity bars across the
screen at what appears to be 16 pixel intervals. The pattern makes the
picture look like it is displayed on a surface with a vertical grooved
texture like
__--__--__--__--__--__--__--__--__--__--__--__--__--__--__
Does this make sense to anyone? The pattern shifts around when there is
any heavy interrupt activity (ie, mouse movements). I get this with my
RAM upgrade removed as well as installed, so if it is a RAM problem, it's
on the basic 512k RAM (Rev. B motherboard). If I had an osilloscope I
might be able to diagnose this myself, but I don't and I can't.
